How put dates on flot - postgresql

Question

I've a little problem, I need to do a curve with on y axis numbers and x axis dates.. but I can't display some dates...
My code :
<script type="text/javascript">
$(function () {
<?php
echo " var data = [";
$cpt="0";
include ('../connect.php');
// Requete SQL
$req = 'select "SPP_NB_IND" from "STAT_PERPHY" where "SPP_SAGES" = \''.$sages.'\' AND "SPP_DATE" between \''.$jourtableau.' 00:00:00\' and \''.$jourfinw.' 23:59:59\'';
$res = pg_query($req);
$reqd = 'select "SPP_DATE" from "STAT_PERPHY" where "SPP_SAGES" = \''.$sages.'\' AND "SPP_DATE" between \''.$jourtableau.' 00:00:00\' and \''.$jourfinw.' 23:59:59\' AND "SPP_NB_IND" IS NOT NULL ';
$resd = pg_query($reqd);
// On met les valeurs obtenues dans un tableau
while ( $row = pg_fetch_assoc ($res) )
{
//echo $row['SPP_NB_IND']."<br>";
$var=$row['SPP_NB_IND'];
while ( $roww = pg_fetch_assoc ($resd) )
{
$abscisse=date('d-m', strtotime($roww['SPP_DATE']));
}
echo "[$abscisse, $var],";
$cpt++;
}
echo "];";
?>
var options = {
lines: {
show: true
},
points: { show: true
},
xaxis: {
mode: "time",
timeformat : "%d/%m"
}
};
<?php
echo "$.plot($(\"#graph1\"), [ data ], options);";
?>
});
</script>
[/CODE]
When I put $abscisse, my curve is vertical and if I put $cpt, I have a "normal" curve... but I want to see dates corresponding with numbers..
Freindly,

See the documentation:
You have to give flot timestamps, not already formated dates. For PHP use something like
$abscisse = strtotime($roww['SPP_DATE']) * 1000;
